[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 2/4 v3] libxl: Change the type of console_mfn to xen_pfn_t
Currently the type of console mfn is unsigned long in libxl. This may be
an issue for 32-bit toolstack running on 64-bit Xen, where the pfn are
64 bit. To ensure that console_mfn can hold any valid 64-bit pfn, the
type of console_mfn is changed to xen_pfn_t.
Also the name console_mfn is misleading as it is actually a gfn. This
patch also modifies the name to console_gfn.
